OB-1 vs opencode
opencode is a strong open coding agent with a broad product surface. OB-1's bet is narrower: a built-in free-model router, durable memory, and compute-matched agent modes inside one terminal workflow.
Choose OB-1 when persistent memory, built-in free models, and self-hosted endpoint portability are the deciding factors.
Choose opencode when you want a larger multi-surface ecosystem with desktop, IDE, GitHub, and hosted model options.
| Question | OB-1 | opencode |
|---|---|---|
| Default route | Start free with built-in free cloud models | Free models advertised, plus provider/subscription connections |
| Open-source posture | Apache-2.0 CLI | Open-source agent ecosystem |
| Local models | Ollama, LM Studio, llama.cpp, vLLM, custom | Broad provider and local-model support |
| Memory | Project memory graph and plain docs | Session/project workflow features |
| Multi-agent shape | Solo, Fusion best-of-N, verified escalation, read-only subagents | Multi-session and built-in agents |
| Best search intent | Free local coding agent with memory | Open-source multi-surface coding agent |
Practical read
- opencode's current public copy advertises included free models, so the honest comparison is not 'free vs not free'.
- OB-1 should win users who care about a free path they control and memory that is visible rather than implicit.
- Both tools should be treated as provider-neutral alternatives to single-vendor agents.
